'Hidden' Parts in sequence diagram

If I add a combined fragment to the diagram which is places over a lifeline and them I will add a note to this lifeline, I’m not able to connect the note to the lifeline. Instead modelio will add the note to the combined fragment.

Steps to reproduce:
– Create a sequence diagram
– add a class to the diagram
– add a lifeline to the class
– add a combined fragment over the lifeline to the diagram
– try to add a node to the life line within the combined fragment

Effect:
– The combined fragment will be selected instead of the lifeline
